[Elecraft] Cut off date for K3 options?

[Dave G4AON]

On the Shipping Status page it states "/At your option we will ship your 
K3 with the standard 5 PPM TCXO and then ship you the TCXO3-1 when it is 
ready - no additional shipping charge". /Should I have been contacted to 
ask what my option will be? Also, is there a cut off date for ordering 
(and perhaps swapping) extra options, e.g. filters?

There seems to be a lack of information/instructions for those of us 
with K3s on order! I haven't received a receipt for the deposit 
either... But get receive an acknowledgement. I assume there will be an 
invoice for the final amount arriving soon...
